Monopolies stimulate capitalism

The argument

The argument treats monopoly profits as the signal that organises investment rather than as a distortion of the market. Supernormal profits lead to new entrants in industries and the desire to get rich: an unusually profitable position advertises itself, and what it advertises is that there is money to be made in that line of business by anyone who can find a way in. The sequence described is therefore temporary by design. In many industries, the first mover may enjoy the benefits of coming up with a profitable idea. The lure of profits will drive others to enter later. A monopoly on this account is the reward for arriving first rather than a permanent condition, and its existence is what summons the competition that eventually erodes it. Remove the reward and the sequence never begins. Without monopoly type profits, there would be little incentive to innovate, because ordinary returns are already available from doing what is being done, at far lower risk. Research and development is costly and uncertain — money is committed before anyone knows whether the result will work, and most of what is attempted does not — so the prospect of an ordinary margin cannot justify it. Only the possibility of an exceptional return is commensurate with the possibility of total loss. That reasoning is already embedded in law, which the argument offers as evidence that it is sound rather than novel. In some cases this initial monopoly is driven by patents and copyrights, and society has chosen to reward patents for centuries in order to motivate inventors to innovate. A patent is a monopoly granted deliberately, for a limited period, on exactly the theory set out here. Monopoly profits are on this account a just reward for innovation, and the mechanism by which capitalism is stimulated rather than an exception to it.

Premises

Counter-arguments

Critics reply that the argument conflates the temporary reward for innovation with entrenched monopoly, and that once established, monopolies tend to suppress the very dynamism the argument credits them with. The prospect of profit does spur innovation, but that is an argument for time-limited patents and competitive markets, not for durable monopoly; a firm that has captured a market has reduced incentive to keep innovating and strong incentives to block entrants, raise prices and buy up rivals. Economists note that sustained monopoly can slow innovation and misallocate resources, which is why competition law exists. The reward-for-innovation point, they argue, justifies patents, not monopoly as a lasting condition.

Rejecting the premises

[Rejecting P1] Innovation needs the prospect of reward, but that is supplied by time-limited patents and the chance of profit in competitive markets, not by durable monopoly. [Rejecting P2] Once a monopoly is entrenched, it has weaker incentives to keep innovating and strong incentives to block entrants and raise prices, undercutting the dynamism claimed. [Rejecting C] Because lasting monopoly can suppress innovation and misallocate resources, the reward-for-innovation point supports patents, not the conclusion that monopolies are good for the economy.
